Well all I was doing was running iMovie while transcoding a file to iDVD, I only had three firefox windows open and listening to my iTunes library. It started getting a little sluggish, so much for macs just work. Ok that was really sarcasm, that was the first time my mini has seemed to finally be pushed to its limits. I put together an hour long movie for my little girls first birthday and was putting into iDVD, I did have a bunch of open windows and the machine started to get a bit sluggish. Overall I still give it an A PLUS because I was told by a lot of people it would be underpowered for what I wanted and it handled it like a champ. The encoding took just over an hour but I had alot of audio pictures and video to put together. After the party I had people asking how much it cost to have the DVD done by a professional and I was thrilled, it turned out perfect. When everyone left I went up and hugged my little mac and told it I loved it. Have you hugged your mac today?
